like so many people, my Seagate external usb drive only worked for a short time with windows 7 64 bit. it appears to be a Windows problem. this external drive works fine with my xp operating system. so i was considering buying an internal hard drive and putting it in an external enclosure, hoping maybe windows 7would consistently recognize it. i have a feeling i will be having the same problems that i'm having now. there seems to be no solution. windows 7 has issues.
